5. Adjust the depth gauge to the desired drilling depth.
6. Tighten the screw at the depth gauge firmly.
7. Tighten the side handle securely by turning the
grip section. This also clamps the depth gauge in
position.
7.1.2 Fitting the insert tool 4
1. Disconnect the supply cord plug from the power
en
outlet.
2. Check that the connection end of the insert tool is
clean and lightly greased. Clean it and grease it if
necessary.
3. Check that the sealing lip of the dust shield is
clean and in good condition. Clean the dust shield
if necessary or have it replaced if the sealing lip is
damaged.
4. Push the insert tool into the chuck and rotate it while
applying slight pressure until it engages in the guide
grooves.
5. Push the insert tool further into the chuck until it is
heard to engage.
6. Check that the insert tool has engaged correctly by
pulling it.
7.1.3 Removing the insert tool 5
1. Disconnect the supply cord plug from the power
outlet.
2. Open the chuck by pulling back the insert tool lock-
ing sleeve.
3. Pull the drill bit out of the chuck.
7.2 Operation
CAUTION
Working on the material may cause it to splinter. Wear
eye protection and protective gloves. Wear breathing
protection if no dust removal system is used. Splin-
tering material presents a risk of injury to the eyes and
body.
CAUTION
The work generates noise. Wear ear protectors. Expos-
ure to noise can cause hearing loss.
CAUTION
Improve the blood circulation in your fingers by re-
laxing your hands and exercising your fingers during
breaks between working.
7.2.1 TPS theft protection system (optional)
NOTE
The power tool may be equipped with the optional theft
protection system. If the power tool is equipped with this
feature, it can be unlocked and made ready for operation
only through use of the corresponding TPS key.

7.2.1.1 Unlocking the power tool 6
1. Plug the supply cord into the power outlet. The
yellow theft protection indicator LED blinks. The
power tool is now ready to receive the signal from
the TPS key.
2. Hold the TPS key or the TPS watch strap buckle
against the lock symbol. The power tool is unlocked
as soon as the yellow theft protection indicator LED
no longer lights.
NOTE If, for example, the electric supply is briefly
interrupted due to a power failure or disconnected
when moving to a different workplace, the power
tool remains ready for operation for approx. 20
minutes. In the event of a longer interruption, the
TPS key must be used again to unlock the power
tool.
7.2.1.2 Activation of the theft protection system for
the power tool
NOTE
Further detailed information on activation and use of the
theft protection system can be found in the operating
instructions for the theft protection system.
7.2.2 Drilling without hammering (A) 7
1. Turn the function selector switch until it engages in
the "Drilling without hammering" position. Do not
operate the function selector switch while the motor
is running.
2. Bring the side handle into the desired position and
check that it is fitted correctly and secured.
3. Plug the supply cord into the power outlet.
4. Position the power tool and drill bit at the point
where the hole is to be drilled.
5. Press the control switch slowly (drill at a low speed
until the drill bit centers itself in the hole).
6. Press the control switch fully to continue drilling with
full power.
7. Do not apply excessive pressure. This will not in-
crease the power tool's drilling performance. Lower
pressure extends the life of the insert tool.
7.2.3 Hammer drilling (B) 7
NOTE
Working at low temperatures: The hammering mech-
anism works only when the power tool has reached a
minimum operating temperature. Bring the tip of the drill
bit or chisel into contact with the workpiece and allow
the power tool to run under no load until it reaches
the minimum operating temperature. If necessary, repeat
this procedure until the hammering mechanism begins to
operate.
1. Turn the function selector switch until it engages in
the "Hammer drilling" position. Do not operate the
function selector switch while the motor is running.
2. Bring the side handle into the desired position and
check that it is fitted correctly and secured.
3. Plug the supply cord into the power outlet.
